St. Louis Cardinals RP Keith Butler (elbow) will need Tommy John surgery after getting confirmation he suffered a tear to his ulnar collateral ligament. Butler was on the Cardinals 40-man roster but had been pitching in Triple-A.

Fantasy Tip:Tyler Lyons is believed to be the replacement in the rotation for Kelly. Lyons won't miss a lot of bats, but he'll have at least two weeks to give you valuable innings in NL-only universes.
